- To all whom it may concern:

Be it known that I, SERGE KANSCHINE,

subject of the Emperor of Russia, residing at Nice, in the Republic of France, have invented ,certain new and useful Improvements in Type-WVriting Machines, of which the following is a specification, reference being had therein to the accompanying drawlng.

The present invention has for its objecta special construction of the keyboard of- .ordinary writing machines with the object of enabling plain or open Writing to be transposed into cipher writing or inversely of t-ranspos-ing cipher writing into ordinary text, the arrangement being such that it is possible to adapt the cipher writing and the deciphering to changing cipher keys.

' The arrangement consists in the fact that the keys ofa writing machine, which are marked correspondingly with the type levers with normal or cipher characters or with both of them, are formed in such a manner, that small plates or caps which carry either normal characters or cipher characters can be interchangeably secured thereto.

Figure '1' of the accompanying drawing- }llzi'stra'tes'in plan the lfzeyboard of awritg'"" machine serving for cipher writing.

Fig-2 is a' section of a key on a larger scale.

Figf'3 sho s the keyboard of a writing machine serviiig for decipheringf' Fig. at a view simi r tOlFig. 2'. Fig. 5 shows the keyboard f a writing machine serving both for writing in cipher and for deciphering.

Any known type of type writing machine can be employed. In the machine intended for writing in cipher which is illustrated in Fig.1, the key plates m andtype-levers (not shown in the drawings) are correspondingly provided with the cipher characters employed, such for example as 21, 36, 45 and so forth; each of the key-plates m mounted on .one of thekey levers n is provided with a,re.ctangular hole 0. In combination with the writing machine thus constructed a series of. small plates a is provided which carrywriting or. numeral characters; the size of these plates corresponds to that of the surface of the key plates m While on their underside they are provided with a rectangularpin t adapted to fit into the angular'hole 0 oneach of the key plates m. Inorder. to. transpose ordinary-matter into chine) the loose cipher character \Vhen it is operated, however, it writes in cipher text and not in ordinary text.

The keyboard of the deciphering machine illustrated in Fig. 3 corresponds entirely with that of an ordinary writing machine and the ordinary characters are provided on the key levers. As in the former case each of the key plates on is provided with a hole 0 for the reception of the pint of a loose plate a. A series of loose plates a is used in conjunction with this machine; on their upper face they carry the several cipher characters employed and on their lower side a pin t adapted tofit into the hole 0 in the key-plates m. In order to permit of deciphering with this machine (which can also be used as. an ordinary writing malates a are arranged on the plates m of t e keylevers n in accordance with the cipher key; by actuating the type levers according to the -cipher text, the latter is transposed by the machine into ordinary text.

It is also possible to provide a single writing machine for writing in cipher and for deciphering. In this case the arrangement is such that both ordinary characters and cipher characters are provided on the acters and cipher characters arearranged on the type levers of the .machine corresponding with the keys and as already described each key-plate is provided with a hole 0 for the reception of the pin 2? of a small plate a. When two series of plates a are used one series having the ordinary characters and' the other the cipher characters this machine can be employed in the following ways: In the normal pos1- tion of the lever h the machine can be used as an ordinary type-writing machine for If cipher plates d are keyplatesm, in accordance with the cipher.

' key when the shift lever h is depressedthe copying of the ordinarytext will produce cipher text.

. I 'A- simple ifrition'aldevice 1- (Fig. 5) can be mounted on the frame of the machine for permanently retaining the shift lever h in its depressed, position.-

Having now described; the invention and in what manner the same is to be used, what Iclaimis: .7 i

A typewriter key-plate marked with any desired character, and having avertical, an- 20 rgular socket therein, a cap marked with any desired character, and an angular depending pinv onsaid cap, adapted to removably engage said socket, as herein set forth.

In testimony whereof I hereunto afiix my 25 signature in presence of two witnesses.
